Urine should be used like a nitrogen based fertilizer, apply it to the roots of nitrogen demanding crops or plants. You can either dilute it one part urine to 3-5 parts water, or just water the plant with fresh water after you have applied the urine. Remember to alternate between plants and not overfertilizer with urine. We usually alternate between plants being fertilized so each plants receives urine once every two to three weeks. If you have a small yard and don’t need all the urine for fertilizer it can be added to the food or yard waste composting bin and will provide extra nitrogen to the compost.
